Submethodologies

Submethodologies

Bioregional assessments are underpinned by methodologies that describe the key approaches used to undertake the assessments. The overarching bioregional assessment methodology is supported by submethodologies that provide further technical details to researchers on how to apply the bioregional assessment methodology. This includes advice on undertaking surface water and groundwater modelling, developing a conceptual model of the bioregion or subregion, dealing with uncertainties and identifying hazards.

List of submethodologies

Each submethodology is briefly introduced in Table 1 below. Links to published content are provided in the title column.

Describes the approach used for surface water modelling, including the model(s) used and underlying assumptions. These surface water models are described in more detail in the corresponding surface water numerical modelling undertaken for each bioregion or subregion.

Describes the approach used for groundwater modelling including the model(s) used and underlying assumptions. It considers surface water – groundwater interactions, as well as how the groundwater modelling is constrained by geology. The groundwater models are described in more detail in the corresponding groundwater numerical modelling undertaken for each bioregion or subregion.

M08

Receptor impact modelling

Describes how to develop receptor impact models that assess potential ecological impacts that might arise at the landscape scale due to hydrological changes caused by coal resource development.

Describes the approaches to determining how sensitive a model is to particular parameters and quantification of uncertainty in the modelled response to coal seam gas and coal mining development.

M10

Impacts and risks

Describes the process to identify and analyse impacts, including how different parts of the assessment logically chain together and how the severity and likelihood of impacts are represented. Results are reported in the impact analysis and risk analysis.
